<h3 id="rationale">Rationale:</h3>
<p>You have specified a shebang that ShellCheck doesn't recognize. This
can be due to invoking the script via a wrapper, specifying a dummy like
<code>#!/bin/false</code> to prevent execution, or trying to check a
script for a non-Bourne shell or tool.</p>
<p>If this really is a sh/bash/dash/ksh script, please add a
<code>shell</code> directive after the shebang to tell ShellCheck how to
interpret the script, as in the example. You can also specify the shell
with the <code>-s</code> flag.</p>
<p>If this is a script in some other language, like
<code>#!/bin/sed</code> for a <code>sed</code> script, then sorry --
ShellCheck does not support <code>sed</code>, <code>awk</code>,
<code>expect</code> scripts. It only supports Bourne style shell
scripts.</p>
